Communion (3rd Sunday of Easter)

You can download the COMMUNION ANTIPHON (PDF score) for the 3rd Sunday of Easter (Year C). The piece is sung by either all men or all women. Those on the top rehearse with the Top Video. Those assigned to the middle use the Middle Video. Those who sing the bottom line use the Bottom Video. (Needless to say, the Latin version can also be sung.) A rather undesirable thing which took place after Vatican II—although not everywhere—was a “de-emphasis” or “neglect” of the Bible. In the pre-conciliar liturgy, the propers were proclaimed at every Mass, but these days many Catholics are clueless about the propers! Approximately 97% of the propers come directly from Sacred Scripture, as the COMMUNION ANTIPHON above demonstrates. You can hear a rehearsal video by clicking here.

“Entrance Chant” • 3rd Sunday of Easter

You can download the ENTRANCE ANTIPHON in English for the Third Sunday of Easter (4 May 2025). Corresponding to the vocalist score is this free organ accompaniment. The authentic version—on the words ómnis térra—sounds exactly like the Hallelujah Chorus from Handel’s Messiah. However, it only sounds that way if you follow Dom Mocquereau’s rhythm, which adds syncopation (in spite of the fact that Mocquereau claimed to abhor syncopation). The Germans do not syncopate the rhythm. If you’re someone who enjoys rehearsal videos, this morning I tried to sing it while simultaneously accompanying my voice on the pipe organ.

We have no endowment, no major donors, no savings, and refuse to run annoying ads. As a result, our mailing list is crucial to our survival.

Antiphons Don’t Match?

A reader wants to know why the Entrance and Communion antiphons in certain publications deviate from what’s prescribed by the GRADUALE ROMANUM published after Vatican II. Click here to read our answer. The short answer is: the Adalbert Propers were never intended to be sung. They were intended for private Masses only (or Masses without music). The “Graduale Parvum,” published by the John Henry Newman Institute of Liturgical Music in 2023, mostly uses the Adalbert Propers—but sometimes uses the GRADUALE text: e.g. Solemnity of Saints Peter and Paul (29 June).

When to Sit, Stand and Kneel like it’s 1962

There are lots of different guides to postures for Mass, but I couldn’t find one which matched our local Latin Mass, so I made this one: sit-stand-kneel-crop

The Funeral Rites of the Graduale Romanum

Lately I have been paging through the 1974 Graduale Romanum (see p. 678 ff.) and have been fascinated by the funeral rites found therein, especially the simply-beautiful Psalmody that is appointed for all the different occasions before and after the funeral Mass: at the vigil/wake, at the house of the deceased, processing to the church, at the church, processing to the cemetery, and at the cemetery. Would that this “stational Psalmody” of the Novus Ordo funeral rites saw wider usage! If you or anyone you know have ever used it, please do let me know.
